Press Release

JEFFERSON CITY---The Missouri Public Service Commission has approved a request filed by Liberty Energy (Midstates) Corp. d/b/a Liberty Utilities (formerly Atmos Energy Corporation) to adjust the infrastructure system replacement surcharge (ISRS) on the bills of its natural gas customers. The surcharge first appeared on customer bills in November 2008.

The ISRS adjustment reflects infrastructure replacement investments made by the natural gas company from October 1, 2010 through May 31, 2012. These costs for natural gas pipeline replacements and relocations are not currently included in Liberty Utilities’ rates.

The current monthly ISRS and the new ISRS for a residential customer in each of Liberty Utilities’ three service areas appears below.
